The Semi-Marathon de Porto-Vecchio is an autumn running event held in Porto-Vecchio, Corse-du-Sud, on the southern tip of Corsica. The primary event is a 21.0975 km road half marathon beginning at the commercial port. Additionally, a 10 km race and an 8 km walk commence from Palombaggia beach, accommodating serious runners, intermediate participants, and walkers, not exclusively half-marathon specialists.
The half marathon route runs from Portivechju towards a finish at Santa-Ghjulia. This coastal path keeps the Mediterranean Sea and the beaches of far southern Corsica in view. The 10 km race shares a similar beachside path from Palombaggia, while the walk offers a more relaxed exploration of the Porto-Vecchio countryside. ASPV Athlétisme and the municipality organize the event, attracting runners from Corsica and mainland France.
